Yes. The 9mm slide does differ from a 357/40 slide in the overall weight and the breech face diameter , however, it is safe to shoot. Your 357/40 magazines will feed 9mm ammunition. You may, or may not, need to use a 9mm recoil spring.

I was hoping to here that. It makes sense that I would need to use the 357/40 mags. The 9mm mags when cycling by hand, won't lock the slide open. It appears the follower on the 9mm mags seen either short or don't stick out far enough.
